向量是一种基本工具,在几何问题的求解中起着重要的作用,教材中对于空间向量给出了几何表示和坐标表示两种形式,可近几年高考立体几何题的标准解答几乎清一色使用坐标向量法(或传统几何法).相比之下,学生对于向量的坐标表示更容易接受和理 Vector is a basic tool that plays an important role in the solution of geometric problems. The textbook gives two forms of geometric representation and coordinate representation for space vector. In recent years, the standard answers to the three-dimensional geometry of entrance examination are almost the same Coordinate vector method (or traditional geometric method.) In contrast, the student coordinates for the vector representation easier to accept
